Tb all 'whom it may cof/wem.' l

Be it known that I, HARRY G. VAN OR- NUM, a citizen of the United States, residing at Newton Falls, in the county of St. Lawrence, State of New York, have invented certain new and luseful Improvements in Paper-Making Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled 'in the art to which it appertains to make and use thesame.

rl`his invention relates to new vand useful improvements in paper making machines,

and particularly to improvements in the Fourdrinie'r machines.

One object of the invention is to provide means associated with one of the slices for adjusting the same toward and away from vthe otherslice, whereby to change the size of the pond and thereby cause the paper fibres to become more closely associated, with a resultant liner grade of paper.

` Figure 1 is a top plan view of a portion of a Fourdrinier paper making machine showing the two slices, and the means for adjusting one of 'them toward andaway from the Figure 2 is a vertical .longitudinal sectional view on the line 2-2 of Figure 1.

Figure 3 is a vertical transverse sectional view on the line 3-3 of Figure 1.

Figure 4 is a side elevation of the portion of the machine shown in Figure 1.

Fig. 5 is anl` enlarged detail, partly in section, of the horizontal and vertical adjusting means for the second slice.

Referring particularly to the accompanying drawings, 10 represents the main frame which supports the breast rolls and which rolls carry the screen beltfor Fourdrinier wire 11. The deelde-.straps are shown at 12 as resting on the screen 11.'

. Extending transversely between the sides 13 of the deckle frame are the slices' 14 and 15, each having the outwardly and downwardly turned ends 16, which overhang e sidesof the deckle frame. On each end o the slice 14 is mounted a rearwardly extending wing 14', which prevents escape. of pulp at the sides of the apron. Through each of the ends of the slice 14 are disposed the ver- 65 tical adjusting screws 17, which pass through longitudinal slots 18 formed in the upper flange 19 of the side 2O of the deckle frame, and rest on the inclined ribs 21, as more clearly explained in my prior Patent #1,-

342,655, issued June 8, 1920. Screws 22 are disposed vertically through the ends of the slice 15, and the lower end of each of these screws is slightly reduced in diameter, as

shown at 23, but with a smooth unthreaded exterior. Resting on the upper face of the flange 19, and adapted for slidable movement longitudinally thereof, is a toothed rack 24, one end of which is disposed between the end 25, of the slice, and the flange. 30

This end of the rack isuntoothed and has a socket 26, in-its upper face, for the reception of the before-mentioned lower end 23 of the screw 22. A lock nut 27 is disposed on each of the screws 17 and 22, for holding 85 the same after adjustment of the slice 1s made, said nut resting on the upper fac'e `of the hook end o f the slice. Secured to each end of the slice 15 is a vertical cleat 28, and

each cleat is formed with an angular boss '29' which rides in and projects through a longitudinal slot 30, formed in the side 20, of the deckle frame, a pin 31 being disposed through the boss, outwardly of the' frame, to prevent through the slot.

. Secured to the side 20, and extending vertically thereabove, are the guides 32 and 33, which serve to hold the rack from lateral sliding movement on the iiange 19. Rotatably supported in the` brackets 32, and extending across the machine, is a shaft 34,

.and ixed on the shaft, and meshing with the rack lates 24, are the gears 35. It will be clear rom the drawing that there are two of crank handle 36, by means of which the Il" shaftv may be rotated, to cause the rack plates 24 to' slide on the anges 19, and

inward .movement of the boss 95 v taneously moving the lendsxof the slice tothereby cause the longitudinal movementof the slice 15, toward and away from the 'slice 14. By this construction, both ends ofthe slice 15 may be adjusted to the same degree,

without the necessity'oi1 going around to` the other side of the machine, the adjustment be readily accomplished from the one side 'of the machine. l

It will be noted that the rack plates 24 are not secured to the slices, their only connection therewith beingby reason of the engagement of the lower ends of the screws 22 in the sockets 26. 'Thus the vertical adjustments of the slice will ynot interfere, in any way, With the longitudinal yadjustment of the slice, with respect to the machine.

What is claimed is: l. In a Fourdrinier machine, the combination with the longitudinally slotted deckle lframe, of a slice' adjustable longitudinally and vertically with respect to the deckle frame, a second "slice movable on the deckle frame toward and away from the first slice, means for adjusting the second slice vertically, and means for simulward and away from the first slice and operatively engaged with the vertically adjusting means thereof. l

2. In a Fourdrinier machine, the combination with the longitudinally slotted deckle frame, of slices adjustable vertically and longitudinally on.I the frame, one vof the slices having guiding and retaining means engaged rthrough the slotted frame, a toothed member on the frame and operatively connected with the last-named slice,

and gear means for engagement with the toothed member for moving the last-named slice. f

3. In a Fourdriniermachine, the com-- bination with the ,y longitudinally slotted deckle frame, of a slice mounted on the frame and having cleats provided with bosses engaged through the slotted frame, toothed plates slidable on the sides of the frame, means engaged with the toothed plates for moving the plates longitudinally of the frame, and means for vertically adjusting the slice and operatively engaged with the `toothed plates.

4. In a Fourdrmier machine, the 'cpmv bination with the sides of the deckle frame,

of a slice disposed for slidable movement on the said sides, a toothed plate slidable on each of the said sides, brackets on the sides engaging in retaining relation to lthe said plates, each .plate having one end disposed beneath an end of the slice and formed with a socketa shaft supported in certain of the brackets, gears on the shaft engaged with the plates, and a screw in each end of the slice for verticallyl adjusting the end of the slice and having its lower end unthreaded and engaged in said socket. j

In testimony whereof, I ailix my signature.
